GEORGE BICKELHAUPT, OF NEW YORK, N. Y.

SCUTTLE LlFTER.

SPECIFICATION forming part of Letters Patent No. 668,&35, dated February19, 1901.

Application filed November B, 1900. Serial Ne. 35.592. (No modeli* TOaZZ whom it fluty concrn:

Be it known that I, GEORGE BICKELHAUPT, a citizen of the United States,and a resident of the city of New York,`borough of Manhattan, in thecounty and State of New York, have invented a new and Improved Scuttle-Lifter, of which the following is a full, clear, and exact description.

The invention relates to Operating mechanisms for sashes, scuttles,skylights, and like deVices--for instance, such as shown and describedin the Letters Patent of the United States No. 639,139, granted to meDecember 12, 1899.

The object of the present invention is to provide a new and improvedscuttle-lifter arranged to permit the operator to easily open or closethe scuttle and to automatically and securely lock the scuttle in aclosed position.

The invention consists of novel features and parts and comhinations ofthe same, as will be-fully described hereinafter and then pointed out inthe clains. i

A practical embodiment of the invention is represented in theaccompanyingdrawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews. a

Figure 1 is a perspective View of the improvement as applied with thescuttle shown in a partly-open position. Fig. 2 is an enlarged sectionalplan View of the same With the scuttle closed and locked. Fig. 3 is asectional side elevation of the same on the line 3 3 in Fig. 2. Fig. 4:is a sectional side elevation of the same on the line Min Fig. 2. Fig. 5is a sectional side elevation of the same with parts in position forswinging the scuttle open,

and Fig. 6 is a cross-section of the same on the line 6 6 in Fig. 5.

The scuttle A is connected by the usual hingesB to the upper end of theframe C, and on the under side of the scuttle A is secured alongitudinally-extending guideway D,preferably made of a square tubehaving a slot in the bottom and provided with transverselyextendingteeth or notches D', as plainly indicated in the drawings. In theguideway D is mounted to travel a friction-roller E, j ournaled on theforward end of a lever F, fulcruned at or near its middle at F' on oneside of the frame O, so that When a swinging motion is given to thelever F in the direction of the arrow a' the friction-roller E causes anupward swinging of the scuttle A into an open position, as shown in fulllines in Fig. 1 and in dotted lines in Fig. 4. A catch G is fulcrumed atH on the forward end of the lever F, and said catch is adapted to engagethe teeth D' of the guideway D, so as to hold the lever F locked to theguideway D and support the scuttle A When in a raised position and atthe time the lever F is released by the operator.

The catch G is provided with a downwardlyextending arm G', having anelongated slot engaged by a pin I' on a spring-pressed bolt or latch I,mount-ed to slide in suitable bearings in a casing 1 Secured to orformed on the forward end thereof, so that when the scuttle A is in aclosed position, as shown in full lines in 4, the latch I engages thesaid keeper J at the time the catch Gr is out of engagement With theteeth D' of the guideway D. (See Fier. 4:.) The catch G is also providedWith an upwardly-extending arm G adapte d to engage one end of a leverK, fulcrumed at or near its middle at K' to the under side of thescuttle A, the other end of said lever engaging a spring pressed latchL, nounted to slide in a casing L', attached to the under side of thescuttle A. The latch L is adapted to engage a keeper N, (see Figs. 2 and3,) secured to the inside of the frane C at the forward end thereof, atthe time the scuttle A is closed, so that the two latches I and Lsecurely hold the scuttle in a closed locked position, and therebyprevent persons from opening the scuttle from the outside of thebuilding. The end of the lever K near the arm G? engages a guideway K tohold said lever in proper position.

On the latch I is Secured one end of a rope O, extending along the underside of the lever F over the pulleys P P', secured to thedownwardly-curved end of the lever F. The rope extends from the pulleyP' horizontally and forwardly and around a pulley P journaled in theforked end of an arn attached to the lever F. The rope then extendsupward and passes over a pulley P Secured to one side of thescuttle-frame O, the end of the rope hanging downward from the pulley 1to be within convenient reach of the operator.

IOO

When the several parts are 'in the position shown in Fig. 4 and thescuttle Ais securely locked to the scuttle-f'ame C by the latches I andL, as previously explained, and the operatordesires to open the Scuttle,it is necessary for the operator to pull on the rope O, so that thelatter first imparts a slding motiop to the latch I and moves the sameout of engagement With its keeper J, and as the said latch I isconnected by the pin I' with the arm G' it is evident that a swingingmotion is given to the catch G, causing the arm G2 to impart a swingingmotion to the lever K, so that the latch L is moved out of engagementwith its keeper N, and consequentlythe scuttle A'is unlocked. On afurther pull on the rope O a swinging motion is given to the lever F inthe direction of the arrow a', so that the Scuttle A is swung into anopen position, and as soon as the scuttle has reached the desired openposition the operator releases the Stress on the rope O, so that thespring of the latch I returns the latter to its outer position and indoing so imparts a swinging motion to the catch G to engage the catchwith the corresponding teeth D' of the ,guideway D. When this takesplace, the lever F is locked to the guideway D, and consequently thelocked parts remain in position with the scuttle open, and the operatorcan *now completely release the rope O.

When it is desired to close the scuttle A, the operator pulls on therope O and imparts a sliding notion to the latch G, so that the latteris moved out of engagement with the teeth D', and upon the operator nowgradually releasing the rope O the friction-roller E Will travel in theguideway D and the Scuttle A Will close by its own weight, and when thescuttle moves into a final closed position on the scuttle-frame C andthe operator releases the rope completely then the latch I engages itskeeper J, owing to the pressure of the latch-spring, and in a similarmanner the other latch L engages its keeper N by the action of thelatch-spring. (See Fig.

By having the catch G pivoted on the lever F the pressnre on the catchby the open scuttle is in the direction of the fulcrum H, so that thespring for the latch I is completely released at the time the Scuttle Ais completely relieved of all strain and the scuttle is open, and thespring is held under tension at the time the operator pulls the rope foropening or closing the scuttle, as above eX- plained.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl.
